Visual Studio Community 2013 crashes when building program from Code-builder

I am using Visual Studio Community 2013 Version 12 Update 4 and OpenCL Code Builder 1.4.0.25 on 64-bit laptop (Windows 8.1, Intel Core i5-5200U and GPU HD Graphics 5500).

I have created a Code Builder project for Windows in C++ and I can build (Configuration: Debug Win32) and run it without any problem.

I have created a session, and Visual Studio always crashes when I try to use following options

Performance issues with Intel MPI (RMA Put/Get) on Xeon Phi

I'm getting bad performance with MPI_Put (and MPI_Get) in IMB-RMA All_put_all microbenchmark on this system configuration:

  • Single and multiple Xeon Phi coprocessors
  • Intel MPSS 3.5.1 (June 2015), Linux
  • Intel MPI Library 5.1.0.079
  • OFED-3.12-1 or OFED-3.18-rc3 (It doesn't really matter.)

Intel MPI runtime environment variables:

offload error: cannot release buffer memory on device 0 (error code 14)

I need your help. 

I tried to run K-means algorithm on Xeon Phi by using offload mode.

But when i tried to get into offload region with the clause '#pragma offload ~~ (as attached pic 1) ' ,

i got an erorr 'offload error: cannot release buffer memory on device 0 (error code 14)' .

I have no idea to solve this problem, and i even cannot find any previous example similar to my problem on google.

I saw offload report by using 'export OFFLOAD_REPORT=3', but i couldn't get any hints. 

plz help me !

regards

How to protect code from triggering MIC build on non-MIC nodes

Hello,
we have two clusters in-house, one with MIC cards and another without. When we build code with OpenMP 4.x pragmas or functions for devices, we get a compilation error on the cluster without MIC cards:

icc: warning #10362: Environment configuration problem encountered.
Please check for proper MPSS installation and environment setup.
testomp.c(1): catastrophic error: *MIC* cannot open source file "stdio.h"
   #include <stdio.h>

  • Random memory read performance difference between GPU and CPU (I7-4770R)?

    We are running a simple code doing random reads and sequential write (i.e. gather operation) on both the CPU and GPU part of the I7-4770R (separately, one at a time) and experiencing 4x slower performance on the GPU compared to the CPU. When doing sequential reads and writes and even random writes, the performance is very similar indicating that both the internals of the chip as well as the memory controller allows the GPU to access the DRAM with the same speed the CPU does.
